Mid cycle bleeding

Ok ladies before I schedule an appointment can anyone maybe give some input.

Ok I am in the green on my glow calendar (ovulation ) and yesterday when I wiped I noticed a little tiny looking blood clot. I figured it was from ovulating I have no cramps at all. Today I wiped and more blood was there not heavy but enough for concern I guess. I am not sure if it is because of ovulation or from a miscarriage . Like I said I'm not in any pain or not cramping .... any thoughts on what is going on ?
